Entail foundation deed by which Cosme de Castro established an entail with all the assets he had inherited from his late wife, Francisca da Cruz, and the third part of his assets. The future administrators were obligated to support the celebration of perpetual masses for the souls of Cosme and Francisca and to bury their remains inside the chapel of Nossa Senhora dos Prazeres, which was going to be erected in Povolide. If the administrators died in Vila Garcia, where most of the entailed assets were located, the annual masses should be celebrated in the chapel of S. João of that place. He appointed his grandson, Agostinho da Cunha, to administrate it.
Belchior de Castro and Maria da Cunha Cerqueira, his wife, attached to this entail the third part of their assets.
